ADOLPH G. KAUFMAN, 0F NEW YORK, N. Y.

T o all whom t may 0071061111- Be it known that I, ADOLPH Gr. KAUFMAN, acitizen of the United States, residing at New York, in the county andState of 'New York, have invented a new and useful Generator, of whichthe following is a specification.

This invention relates to incandescent lamps where the hydrocarbon fluidis vaporized and burned in connection with one, or more incandescentmandes-preferably two; and the drawing shows a burner head adapted toutilize two mantles for lighting purposes. The object of my invention isto provide a generator, or vaporizer in which the hydrocarbon lluid willbe converted into gas so constructed that a match can be used in anefficient manner for starting purposes; a further object of my inventionis to provide a generator so constructed that the generator and coil canbe rotated'without breaking the mantle, or mantles of the lamp; toprovide an increased heating portion without danger of the formation ofcarbon; and to provide a generator with strainers so constructed andinserted that the hydrocarbon fluid will not be retained in the coil.

The invention is illustrated in the accompanying drawing, in which-Figure 1, is an elevation of a burner head of a lamp, and of my improvedgenerator applied thereto-parts being broken away to show theconstruction;

Fig. 2, is a plan view of the generator;

Fig. 3, is an enlarged view of the top part of the generator, showingone form of attaching the head; and,

Fig. 4, is a plan view of a modied form of generator.

In the drawing like numerals of reference refer to the same parts ineach of the views.

In practice I provide a generator 5, with a coil 6, formed without thezone of the mantles 7 In the drawing but one mantle 7 is shown, but thelamp head has the usual mixing chamber 9, and two burner tubes 10 and11, so that two mantles 7 will be employed, suspended below the airintake 8, and adjacent to the coil 6 so that the heat of the mantles, inincandescence, will be radiated directly upon the coil, and yet the coilwill be free to rotate in removing the generator without possibility ofbreaking the mantles with the coil, as will be clear. The burner head,it will be observed, `is vnot supported by the generatorgf but is whollysupported by Specication of Letters Patent.

the single standard 12, which may have an extension 13, on which theshade holder 14 is adjustably mounted in a reversible manner, as will beclear.

In practice I prefer to mount on the top oi the generator a removablenozzle 15, as more particularly shown in Fig. 3. rlhe nozzle 15, may bemounted in a nut 16, fastened on the generator 5, or the nozzle may besecured on the generator in any desired manner, as the method by whichthe nozzle is secured to the generator forms no part of my presentinvention. The desirable feature of my invention, however, lies in thefact that the nozzle 15 will fit in the orifice 17 in the manner shownin Fig. 1, to leave the space 18 between the nut, or head 16, and thebottom of the air intake 8. By having this nozzle lit in the orifice, asdescribed, the generator 5 may be very small in diameter while thenozzle will fill theorifice in the burner head adapted to receive anordinary generator, or a generator, or vaporizer of any construction.

By having the space 18, and the nut, forming the head, or stop, asshown, the generator can never beraised a sufficient distance to bringthe coil 6 into contact with the mantles 7. Thus the head, or nut 16forms a stop to limit the raising of the generator, as will be clear.

In practice I prefer to mount a preheating cup 19 on the generator, sothat in starting the lamp a preheating fluid may be placed in this cupin the ordinary manner in starting the lamp, or a match can be used forthis purpose.

Where a match is used for starting the lamp it is designed to have thecoil 6 Sulliciently close to the cup 19 that a match 20 will rest withinthe coil 6 and engage the cup 19, as shown, so that the cup will formthe rest for the match. Thus, in burning, the flame ofthe match willascend, as will be understood, and generate sufficient heat to start thelamp thereby enabling the lamp to be started with a less number ofmatches than would be necessary with the coil in a different position.

It will be understood that the cup 19 need not be used for the purposeof supporting the match, as any ledge, or project-ion placed adjacent tothe coil 6 on which the match might rest inl burn-ing would answerthepur.- pose of assisting the' coil 6 in supporting the matchduring'colnbustion. It will-be understood, also, that since the coil isdisposed in a horizontal manner, a match might be rested on the same inburning, as shown in dotted lines in Fig. 1. By making the coilhorizontal the vaporization of the hydrocarbon liuid will beaccelerated, as will be understood, by reason of the fact that the bend2l, lies adjacent to the bend 22 just below the coil, so that theascending fluid to be vaporized will be in a position to receive theheat from the match in starting. After starting, the heat ofincandescence of the mantles will readily generate the vapor in the part23 of the generator; and this action will be more certain by reason ofthe fact that the coil 6 lies within the heat zone of the mantles sothat the hydrocarbon fluid in ascending will be heated within` the coilbefore reaching the part 23. In practice I prefer to mount a strainer 24in the part 23 of the generator, and may also mount a strainer 25 in thelower, or part 26 of the generator. It will be noticed that neither ofthese strainers extend into the coil 6 so that there is a clearpassageway 27 within the coil in which the hydrocarbon fluid may lieafter passing through the lower strainer, or upward from the font, notshown, to the part 23 of the generator where it isv converted into gasfor commingling with air and combustion.

It will be understood that I may use any method of construction that maybe desiredy for the purpose of removing, and inserting the strainer, orstrainers, without departing from the spirit of my invention. Inpractice it is desirable to keep the generator clean; and thisnecessitates the removal of the strainers in many cases. It isdesirable, therefore, to provide a strainer, and al construction bywhich the removal and renewal can be accomplishedreadily, and with theloss, of as little time asfpossible. Consequently, as the necessity isso urgent, any

desired construction may be employed; and

it is not thought necessary to illustrate the various methods.

By using two mantles I bring each mantle into close contact Vwith thecoil 6; and by making the coil 6 inthe preferred form, as shownspecially in Fig. 2, the coils 2S, will bring the iuid into closecontact with each mantle, as will be understood.

In Fig. 4 I have shown a coil 6 of differ* ent construction than shownin Fig. 2, in which the generator is not crossed. A generatorconstructed in this way will work successfully, but is not as desirableas the construction shown in Fig. 2. In this construction I have shownthe preheating cup 19 on the generator.

Where the cup is used, I prefer to fix'it on the generator so thegenerator'can be ref-.-

tated with this cup instead of having to use a tool. As stated above,the generator can to bend the part 29 as shown, and thereby form theloops 28 in the coil.

In operation, the hydrocarbon fluid, as gasolene, or kerosene is fedtothe generator through the burner valve 30. As the fluid ascends it isstrained through the strainer 25 after which it iills the coil 6, andlies there till ready to be taken up by the part 23. In starting thelamp the flame of the match will supply the heat to start the initialvaporization. Owing to the construction of the generator usually onematch will be suiiicient to generate sufficient gas to .start the lamp.If not, anothermatchcan be readily lighted and placed in position forstarting purposes. When the lamp is started, theV My invention lies inthe formation of the generator tube, as described above so the generatorcan; be removed withouty any danger whatever of breaking the mantles;and this is a very important feature since it is generally necessary tofrequently remove the generator for the purpose of cleaning, or needlingthe dischargeY orifice in the generator nozzle; and it would be aserious matter, and add much to the costof operation of the lamp if the'mantles were broken each V.time `it was necessary to remove thegenerator.

I know that coils have been used in the generator; but believe I havemade a substantial improvement in so locating the coil that it will forma part of the match holding means, and also in that the coil lies whollywithout the zone of the mantles.

'Ihe construction is simple in operation; and efficient in use.:

I claim: j

1. Inan incandescent light,a plurality of suspended portion thereofbetween the mantles and having a horizontal coil outside of the zone ofthe mantle whereby the generator can be rotated without breaking themantle.
